The vulnerability allows a local user to conceal capability changes in audit records.

The vulnerability exists due to incorrect data recording in __audit_log_capset() in the audit subsystem when logging CAPSET operations. A local user can modify inheritable capabilities to conceal capability changes in audit records.

This can mask preparation for a privilege-escalating exec in audit data used for compliance and forensic analysis.
